DRAM init would require in - TPL stage if target support TPL and - SPL stage if target support SPL alone So, don't initialize the dram in SPL if TPL defined and at the same time enable it if TPL undefined which is SPL alone. Tested in TPL and SPL supported boards. Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> --- arch/arm/mach-rockchip/rk3399-board-spl.c | 2 ++ 1 file changed, 2 insertions(+)
